Re:Build Answer Engineering has developed a scalable aeroelastic simulation approach to analyze VTOL transitions from hover to forward flight, one of modern VTOL design’s most complex aerodynamic challenges. Our simulation combines mid-fidelity aerodynamic and structural tools to capture critical interactions between rotors, motor mounts, booms, and wings in a multi-physics environment. This provides deep insight into aeroelastic stability, helping engineers identify potential instabilities before they become costly problems. Our process leverages cloud computing to evaluate a wide range of flight conditions in hours rather than months. This accelerated analysis helps customers bring safer, more efficient VTOL aircraft to market faster.
The workflow begins and ends with full-fidelity finite element meshes while using mid-fidelity aeroelastic simulation in the middle to generate solutions in a reasonable time. The key differentiation of this approach from other options is the use of viscous vortex particle aerodynamic methods, multibody structural representations, and the ability to solve aero-structural solutions at a speed suitable to calculate an entire VTOL transition flight envelope each day.
Using cloud-based simulation resources, we leverage parallel processing of hundreds of flight states, reducing simulation time from months to hours. This scalability allows for comprehensive evaluation of a vast matrix of flight conditions, supporting design optimization and reducing the risk of costly prototype failures.
We can help your team integrate a multi-body dynamic aeroelastic approach into your VTOL lift system design to predict potential risks and solutions better. Ideally, aeroelastic trade studies can be performed early in the program. However, if the design is complete, existing structures can be analyzed using deflection-based criteria to identify and address any aeroelastic issues across the transition flight envelope.
We have developed postprocessing tools that, combined with cloud computing, enable rapid simulation results in hours instead of months. This streamlined process provides straightforward, actionable insights through easy-to-read charts highlighting structural failure risks across the VTOL transition flight envelope.
